SCD40 SCD41 Gas Sensor Module 2.4-5.5V Detects CO2 Carbon Dioxide Temperature and Humidity Sensor I2C Communication

SCD40/SCD41 has high precision and high cost performance. The module leads out the power supply and communication pins with a 2.54mm pitch pin interface. On-chip temperature and humidity compensation is achieved through the built-in temperature and humidity sensor to measure humidity and temperature. SCD40/SCD41 can realize intelligent adjustment of indoor ventilation system according to carbon dioxide concentration. Indoor air quality helps to maintain a healthy and efficient environment under low carbon dioxide concentration for a period of time.
